This is out of this world impressive work and fun to read about, @AqeeAqee!!! Thanks for your efforts and this update with detailed descriptions!
-No doubt very good news and a great help for everyone interested in getting MCA games playable on the Pico(and getting these two great tinker communities(MakeCode and Raspberry Pi) closer to eachother and sharing great ideas and inventions!)
That was nice to read, thanks; nothing is more motivating when programming than knowing that at least one other person on the planet finds it useful! 
I can only respond with ditto thanks for all your contribution like here, your amazing extensions and lately for the advances in MCA 3D graphics. It is no secret that I would love to see you and some other people on this forum who know who they are collaborate on a first ever demo compo entry.
(Sadly, my own abilities are put to best use as audience and fan in this particular matter.)
